We are hearing about the Corona virus because a new new version evolved from the existing versions. That new version has much more virulent effects and can be transmitted between humans.
This is evolution in action and can be observed almost in real time, because viruses have very short generation times and can therefore evolve quickly. You can deny if you wish, but if you get infected with this new evolutionary strain you are likely to be very sick.
Someone will probably say: "But this is a virus, I'm not talking about viruses." It's true that evolution is much harder to observe directly in organisms with longer generation times because change tends to take much longer, but the principles are exactly the same.
